Set in Chicago in the 1980s, Glengarry Glen Ross still resonates today with its condemnation of American business and the testosterone-filled culture that runs it. In a world where you eat what you kill, men are driven to desperate measures to survive, and thrive in a twisted hierarchy of “real men” and competition for big-ticket prizes.

The story opens at the local Chinese restaurant, where we get a lay of the land and a taste of its inhabitants. Veteran salesman Shelly “The Machine” Levine (Daryn DeWalt) has been in a serious slump and makes a desperate plea to office manager John Williamson (Chris Coculuzzi) to get some prime leads. The outraged Dave Moss (Neil Hicks) vents to his side-kick co-worker George Aaronow (Jerrold Karch), hatching a plan to take the good leads by force and put them to use for their own benefit. And the slick Richard Roma (Derek Perks) spots a mark in the shy, unassuming James Lingk (Abbas Hussain).

With Act Two opening on their pillaged office, Detective Baylen (Frank De Francesco) has taken up residence, interviewing each man one by one. Shelly seems to have emerged from his slump – and big time. And Roma is celebrating record sales, earning him a car. That all changes when a sheepish James arrives, putting that deal in jeopardy. Loyalties are tested and stand-offs get ferocious as things go to hell, and we get closer to discovering who broke in and stole the leads.

Nice work from the entire cast in this intense, hot-tempered and darkly funny Mamet classic. Stand-outs include DeWalt, who finds a great balance between flop-sweat desperation and cocky showmanship as Shelly Levine; it’s a roller coaster of extreme highs and lows as Shelly fights for his livelihood, vacillating between winning and losing. Perks is a charming scoundrel as Roma; a suave and seductive player, and a sharp marksman, Roma is nevertheless a thoughtful philosopher and a loyal guy—crediting Levine as his mentor. Just don’t get on his bad side.

Coculuzzi gives us an icy, detached Williamson, who’s a bit of a cypher; the company ‘Yes man,’ Williamson’s a classic case of management who knows zero about the work he’s managing—and who deeply enjoys the withholding and proffering of power. And Karch gives a compellingly understated and comic performance as George Aaronow; a quiet, sweet guy, Aaronow may have been duped by Moss, but he knows how to look after himself.

So what if I told you that, up until the 70s, radical mastectomy was the go-to procedure for Stage One breast cancer (e.g., a pea-sized tumor)? You’d likely be a bit shocked, puzzled and possibly enraged. Right? I know I was.

Directed by Edgar Chua, Radical has a fine cast: Jane Smythe gives a very strong performance as the sharp, wry-witted and kind workaholic Peters; and Susan Q. Wilson is a picture of efficiency and protective concern as Peters’ nurse colleague Helen. Sheila Russell is a force to be reckoned with as the feisty, good-humoured, no-bullshit feminist activist Professor Rose Levine – who is more than happy to lock horns with Jerrold Karch’s cantankerous, arrogant and narrow-minded Chief of Surgery Dr. Fowler. And Jeff Yung is endearing and gutsy as the put-upon, forward-thinking young surgeon Frank.

Peters is eventually forced to make some critical treatment decisions herself when she gets her own diagnosis. But throughout the course of this play, we see that her push to examine the efficacy of, and ultimately implement, the lumpectomy wasn’t just a struggle for women’s health/rights, but for all patients’ rights – striving to afford patients the compassion, respect and decision-making power they deserve within the health care system. Hayter’s play gets to the heart of the Hippocratic oath maxim “Do no harm;” it must extend to treatment procedures – providing a good outcome, while keeping the possible negative impact on the patient in mind.

On a personal note – as someone who’s had a hinky mammogram result, a negative biopsy and ongoing mammogram follow-up to keep an eye on the suspicious particles – I’m very glad and grateful that Peters’ work resulted in the possibility of keeping my breast, should the need for surgery come to pass.

Radical is a sharp-witted, informative and moving telling of Peters’ fight for the lumpectomy.
